Seylora

A Nivoda alternative for Sri Lankan sapphires and rubies

Nivoda is a London based B2B marketplace best known for diamonds, which added coloured gemstones and relaunched its gemstone marketplace in February 2026. Seylora is narrower by design: a gemstone supplier network for Sri Lankan sapphires and rubies. This page sets out where each one fits so you can choose the right source for coloured stones.

When Nivoda is the better fit

  • You need diamonds, lab grown diamonds or melee alongside coloured stones from one supplier.
  • You want the widest range of gemstone varieties from many countries in one marketplace.
  • You prefer a single large platform that also handles finished and custom jewelry.

When Seylora is the better fit

  • You sell Sri Lankan sapphire and ruby and want origin specific sourcing, not a global mix.
  • You want every stone listed in the same format, with treatment and certificate evidence labelled the same way.
  • You want reservations that cannot double book and supplier confirmation before an order is placed.
  • You want to put Sri Lankan stones on your own website through an API with a sandbox for testing.
